Greta uses 4 ounces of pasta to make 4/5 of a serving of pasta. how many ounces of pasta are there per serving?

Take 4oz. In a fraction. 4/1. Divide 4/1 by 4/5. When your dividing fractions the divisor ( the second fraction) is flipped.

So then it will be 4/1 multiplied by 5/4 which is 20/4 which is 5. So 5 Oz. Per serving.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
